Features & Product Details

The Supreme SP for the Subaru STI hatchback features a large horizontally mounted, 3-section muffler with a center inlet. This routing allows for the large 3” diameter piping to more smoothly enter the muffler’s center section. Exhaust gases exit each side of the revised muffler via the two 2.5” diameter piping to quad staggered 3.5” GReddy double-wall slash cut tips, The non-tapered 3” mid-pipe also encases a large resonator section to tune-out drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.

  • Q: Donut gasket adapter  doucheung08710283 months ago

    May I know which adapter I should get for a stock downpipe? Is that already included in the GReddy Catback already? Thanks
  • Q: Gaskets included  FLStef10 months ago

    According to Greddy's product page on their website the cat back system includes only two gaskets. They say "reuse factory doughnut-gasket and hardward for mid-pipe." I would like to replace this with a new one, can you supply the part number please. Thank you.

  • Q: Fit on 2012 WRX hatchback?  newbiesubie10 months ago

    Will this exhaust fit a 2012 non-STI WRX? I noticed this exhaust specifically lists WRX STI and not WRX so I wanted to double check before picking it up.
  • Q: Fitting.   idmantis3 years ago

    I selected that my vehicle is a 09 wrx SEDAN not a Hatch. This came up as a compatible exhaust. Is it?
  • Q: Stock fitment   Hinkmeister 3 years ago

    Does this exhaust bolt up to stock down pipe?

      A:  This will work with the OEM downpipe. It is highly recommended that you run the Grimmspeed OEM downpipe to 3" catback adapter with a new OEM donut gasket to prevent any leaks.
